Abstract

The present experimental work aims to give an objective assessment for the integrity of bone due to crack existence. A simple, non-invasive and practical method for detection of bone cracks and monitoring the healing progress of bone fractures was presented. The technique used is based on monitoring shock wave propagation in a long bone with a progressively increasing defect in the bony cortex. Significant relationships were found between the relative size of the bone discontinuity, and the resonance frequencies, the transmission coefficient, the wave velocity, the transit time across the fracture and the transmissibility.
